Lake Anderson is one of several lakes that offer fishing within easy reach of South Bay residents. It is primarily a bass, panfish and catfish lake.
This 7-mile-long reservoir sits in the South Bay region near Morgan Hill. The lake features varied structure including rocky points, coves along the north shore, and productive narrows at each end.
Facilities at Anderson include a full-service marina, launch ramps and picnicking. Camping and night boating are not permitted at this 7 mile long lake.
Power-boating and waterskiing are popular on weekends, so angling is best on weekdays and early in the day.
Spring brings the best bass action as water temperatures climb into the 58-65°F range. Largemouth bass move into the shallows for spawning, making them accessible to shore anglers and boat fishermen alike.
During these months, bass concentrate near rocky structure and vegetation. Post-spawn fish often suspend near drop-offs where they ambush baitfish recovering from their own spawning activities.
Summer heat pushes bass deeper into the 35-50 foot range as surface temperatures exceed 75°F. These fish seek cooler water near the thermocline where oxygen levels remain adequate.
Catfish become increasingly active as temperatures rise. The warmest months produce the most consistent catfish action, though these fish can be caught year-round with proper techniques.
Fall conditions trigger aggressive feeding as bass and other species prepare for winter. Water temperatures dropping back through the 60s reactivate shallow feeding patterns.
Panfish including bluegill and crappie school up during fall. This concentration makes them easier to locate and catch in numbers once a productive area is found.
At Anderson, bass fishing is best near the rocky point by the dam, in the coves in the north shore of the lake, and in the narrows at each end of the lake. Catfishing is good at the E. Dunne Avenue bridge, near the marina and at the dam.
The rocky point by Anderson Dam holds bass throughout the year. The depth changes and irregular bottom create ambush points that bass use to trap baitfish against the rocks.
North shore coves provide protection from wind and boat traffic. These areas warm quickly in spring and offer shade during summer, making them productive in multiple seasons.
The narrows at each end of the lake funnel baitfish through confined areas. Predator fish station themselves in these bottlenecks to intercept passing prey.
The E. Dunne Avenue bridge creates current breaks and shade that attract catfish. The structure itself provides cover while the adjacent channel offers access to deep water.
Bass are deep in summer, from 35-50 feet. One good way to go down to bass at these depths is to jig a spoon vertically.
Drop it straight down to the bottom, lift it up a few feet, and let it flutter down. Bass strike on the initial drop and on the flutter drop.
Vertical jigging works particularly well when fish are suspended over deep structure. Modern electronics help identify these suspended fish and the structure they relate to.
Jerkbaits produce excellently during spring when bass are shallow. These baits imitate injured baitfish and trigger reaction strikes from aggressive fish.
Texas-rigged plastic worms remain a South Bay favorite. Purple and brown are traditional colors, with darker shades working well in stained water.
Crankbaits that dive to the 15-20 foot range are effective during transitional periods. The Rebel Deep Wee R has proven particularly productive at Lake Anderson.
Spinnerbaits shine in stained water and around vegetation. These versatile lures can be worked at various depths and speeds to match fish activity levels.
Topwater plugs create explosive strikes during low-light periods. Early morning and evening sessions near points and coves produce memorable surface action.
Clams, anchovies and chicken livers work well for catfish. These natural baits produce the strong scent trail that catfish use to locate food.
Fresh bait consistently outperforms frozen options. Changing baits every 30-45 minutes maintains maximum scent dispersion in the water.
Bottom rigs with sliding sinkers allow catfish to take line without feeling resistance. This presentation results in more hookups compared to fixed-weight setups.
Catfish often feed more aggressively at night during summer months. Evening sessions starting an hour before sunset extend fishing opportunities for working anglers.
The dam area concentrates catfish due to deeper water and current from water releases. Position baits where current meets calmer water for best results.
Channel catfish at Anderson typically range from 1-4 pounds. The marina reports some much larger catches, particularly during summer months when big fish feed heavily.
Patience is essential for catfish success. These fish may take 15-30 minutes to locate and commit to a bait.
Multiple rods allow anglers to cover different depths and locations simultaneously. Check local regulations regarding the number of rods permitted per angler.
Bluegill and other panfish provide excellent action for beginning anglers and families. These fish are aggressive and relatively easy to locate during warm months.
Small jigs tipped with worms or grubs work exceptionally well. The Fle Fly-style jigs in 1/32 to 1/16 ounce sizes are local favorites.
Crappie fishing peaks during spring when these fish move shallow to spawn. They concentrate around submerged structure including brush piles and fallen trees.
Experienced anglers recommend downsizing tackle for crappie. Smaller jigs and light line produce more strikes from these notoriously finicky feeders.
Live minnows remain the gold standard for crappie fishing. Suspend them under a slip bobber at the depth where fish are holding.
Panfish often school in predictable locations. Once you catch one fish, work the area thoroughly before moving.
Trout are the standby species at Chabot. This statement from adjacent Lake Chabot applies to many South Bay waters.
While Anderson isn’t primarily known as a trout fishery, stocked trout provide action during cooler months. Check with the marina for current stocking schedules.
There is trout action in Coyote Creek below Anderson Dam. This tail water fishery extends fishing opportunities beyond the lake itself.
Garlic marshmallows and salmon eggs are top baits. These prepared baits work well for stocked trout that were raised on pellet feed.
Trolling is a popular angling technique as is anchored and shore fishing with a sliding sinker rig. Trolling allows anglers to cover water and locate active fish.
Spinners and trout spoons like Kastmasters in 1/8 ounce gold are good at lake inflows or when fish are near shore. These lures imitate small baitfish that trout target.
Morning sessions typically produce best for trout. These fish prefer cooler water temperatures and often move deeper as the day warms.
A medium-power spinning rod in the 6'6" to 7’ range handles most Lake Anderson situations. This versatile setup works for bass, catfish, and panfish.
Match the spinning rod with a reel in the 2500-3000 size class. Spool with 8-12 pound monofilament or 10-15 pound braided line.
Baitcasting tackle provides advantages for bass fishing around heavy cover. A medium-heavy rod with a fast tip gives the power needed to extract fish from structure.
For catfish specialists, a medium-heavy 7-7'6" rod with good backbone handles the runs of larger fish. Pair with a reel that has a smooth drag system.
Line selection depends on water clarity and cover density. Fluorocarbon leaders help in clear water while straight braid excels in vegetation.
A well-stocked tackle box for Anderson should include a variety of plastic worms, jigs, crankbaits, and spinnerbaits. Color selection matters less than having the right presentation for current conditions.
Bring multiple types of sinkers and hooks. Slip sinkers for catfish, split shot for finesse presentations, and a selection of hook sizes from #6 to 4/0.
Weekdays offer the best fishing due to reduced boat traffic. The lake sees heavy recreational use on weekends and holidays.
Early morning fishing from first light until mid-morning produces consistent action. Fish are most active during these cooler, calmer hours.
Water clarity varies with rainfall and irrigation releases. Stained water conditions call for darker lures and stronger scents.
Wind can be your friend or foe depending on approach. Windblown shorelines concentrate baitfish but make boat control and casting more challenging.
Pay attention to water releases from the dam. These create current that activates fish feeding behavior throughout the lake.
Barometric pressure affects fish behavior at Anderson as it does everywhere. Falling pressure before a storm often triggers aggressive feeding.
Cold fronts typically slow bass activity but can improve catfish fishing. Adjust techniques and expectations based on recent weather patterns.
The full-service marina provides boat rentals, bait, tackle, and fishing information. Staff can advise on current conditions and hot spots.
Multiple launch ramps accommodate various boat sizes. Arrive early on weekends as ramps become congested by mid-morning.
Shore fishing access exists at several points around the lake. The areas near the marina and dam provide the most accessible bank fishing.
Picnic facilities allow families to combine fishing with other outdoor activities. This makes Anderson an excellent choice for mixed-interest groups.
Parking is available near major access points. A day-use fee applies to most areas.
The lake’s proximity to San Jose and South Bay communities makes it accessible for after-work fishing sessions. Drive time from most areas is under 45 minutes.
A valid California fishing license is required for anglers 16 and older. Licenses are available at the marina and sporting goods stores.
Familiarize yourself with current bag and size limits for each species. Regulations can change seasonally, so verify current rules before fishing.
No camping or night boating is permitted. Plan trips that conclude before official sunset times.
Life jackets are required for all boat occupants under 13 years old. Adults should wear them as well, particularly in rough conditions.
Be aware of boat traffic, especially during busy weekends. Establish a lookout if fishing from an anchored boat.
Summer temperatures can be extreme. Bring adequate water, sun protection, and shade.
Respect private property around the lake. Only access the water from designated public areas.
Contact Anderson Lake County Park at (408) 779-3634 for current information. Staff can advise on conditions, regulations, and recent catch reports.
Consider fishing pressure when planning your trip. Weekday visits provide a more peaceful experience with less competition for prime spots.
Keep detailed notes about successful patterns. Water temperature, time of day, exact locations, and productive baits all inform future trips.
Don’t be afraid to change tactics if your initial approach isn’t working. Versatility often separates successful anglers from those who struggle.
